Patrick McMenemyEd Keetz used to have a pre-1976 Albany Show which I attended several times.
I was able to pick up a 1914 Chief Meyers Pritchard Stamp, and a 1910 era Roger Bresnahan writing tablet at one of the shows about 5-6 years ago. I am not sure of what he has at the Latham NY show(s) with regards to vintage material.
